// CLASS:    MPolyMessage
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MPolyMessage)
//
// This class is used to register callbacks for poly messages.  Currently,
// you can use this class to listen to component id changes for vertices,
// edges and faces.
//
// To remove a callback use MMessage::removeCallback.
// All callbacks that are registered by a plug-in must be removed by that
// plug-in when it is unloaded. Failure to do so will result in a fatal error.
